In the audio clip, Hummel can be heard in panic as he talks to the operator. He says: ‘I had my gun and I pulled the trigger and I didn’t realise there was a bullet in there and I just shot my daughter. Oh god. Oh my god no. Oh my god no.’

The operator suggests he performs CPR while awaiting emergency services.

Hummel was arrested and charged with neglect of a dependent resulting in death, battery resulting in death to a person less than 14-years-old, reckless homicide and two counts of neglect of a dependent.

He faces 40 years in prison on the first charge alone.
